iPhone batteries are rated to hold 80% of their capacity for up to 500 charge cycles, which lasts roughly 18-24 months for most users. After that, your iPhone may need to be charged far more frequently, and iOS may warn you that performance is affected (in other words, your phone will run slower). Use this guide to replace your battery and restore your iPhone to like-new performance.
If your battery is swollen, take appropriate precautions.
Note: After the repair, your iPhone may display a warning about the “genuineness” of the battery, even when using original Apple parts. If your iPhone functions normally, you can safely ignore the warning.
You’ll need replacement adhesive to reattach components when reassembling the device.
What you need
-
-
Power off your iPhone before beginning disassembly.
-
Remove the two 6.7 mm-long pentalobe screws at the bottom edge of the iPhone.
-
-
-
Use a hairdryer or heat gun or prepare an iOpener and apply it to the lower edge of the iPhone for about two minutes in order to soften up the adhesive underneath.
-
-
-
Pull the blue handle towards the hinge to disengage opening mode.
-
Position the suction cups near the bottom edge of the iPhone—one on the front, and one on the back.
-
Push down on the cups to apply suction to the desired area.
-
-
-
Push the blue handle away from the hinge to engage opening mode.
-
Turn the handle clockwise until you see the cups start to stretch.
-
Wait one minute to give the adhesive a chance to release and present an opening gap.
-
Insert an opening pick under the screen when the Anti-Clamp creates a large enough gap.
-
Skip the next two step.
-
-
-
If you're using a single suction handle, apply it to the bottom edge of the phone, as close to the edge as possible.
-
If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.
-
-
-
Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.
-
Insert an opening pick into the gap.
-
-
-
Slide the opening pick around the bottom right corner and along the right edge of the iPhone, slicing through the adhesive holding the display in place.
-
-
-
-
Pull on the small nub on the suction cup to remove it from the front panel.
-
If you used an iSclack and it's still affixed to the iPhone, remove it now.
-
-
-
Open the iPhone by swinging the display up from the right side, like the front cover of a book.
-
Lean the display against something to keep it propped up while you're working on the phone.
-
-
-
Remove the 1.25 mm-long Y000 screw securing the battery & display connector cover bracket.
-
-
-
Use a pair of tweezers to remove the battery & display connector bracket.
-
-
-
Use a spudger or a clean fingernail to pry the battery connector up from its socket on the logic board.
-
Bend the connector slightly away from the logic board to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.
-
-
-
Use a spudger or a clean fingernail to pry the OLED panel cable connector up from its socket on the logic board.
-
-
-
Remove the five 1 mm-long Y000 screws securing the front sensor assembly cover bracket.
-
-
-
Use a spudger or a clean fingernail to disconnect the front sensor assembly cable connector.
-
-
-
Remove the four 1.5 mm-long Phillips #000 screws securing the speaker.
-
-
-
Peel down the first battery adhesive pull-tab to un-stick it from the bottom edge of the battery.
-
-
-
Grab the pull tab with your fingers and slowly pull it away from the battery, toward the bottom of the iPhone.
-
Pull hard enough to maintain tension on the strip, but don't force it. Give it plenty of time to stretch and un-stick from under the battery.
-
Don't press down on the battery. Hold the iPhone firmly by its sides.
-
Keep the strip flat and unwrinkled. Try to pull evenly on the whole strip, rather than pulling mainly in the middle or on one side.
-
Pull at a low angle so the strip doesn't snag on the edge of the battery.
-
If the adhesive strip breaks off, try to retrieve it using your fingers or blunt tweezers, and continue pulling—but do not pry under the battery.
-
-
-
Grab the pull tab with your fingers and slowly pull it away from the battery, toward the bottom of the iPhone.
-
Repeat the previous procedure on the two remaining pull tabs.
-
Wait about one minute for the alcohol solution to weaken the adhesive.
-
Use the flat end of a spudger to gently lift the battery.
-
-
-
Remove the battery.
-
If there's any alcohol solution remaining in the phone, carefully wipe it off or allow it to air dry before installing your new battery.
-
If possible, turn on your device and test your repair before installing new adhesive and resealing.
Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the device at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.
To reassemble your device, follow the above steps in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
For optimal performance, after completing this guide, calibrate your newly installed battery.
Take your e-waste to an R2 or e-Stewards certified recycler.

I don't think it's stated clearly enough that the display adhesive is VERY strong and you might think you've gotton a big enough gap when sticking in a pick will actually separate the layers of the screen and break it (defintely not speaking from experience). Make sure the phone is totally, thoroughly heated and be very, very careful.
